FIG. 1 , there is shown a portable printer generally indicated at 20 having ahousing 21 with adoor 22 at the front of theprinter 20. Thedoor 22 has anouter panel 22′ and aninner panel 22″ (FIGS. 2 and 18 , for example). Theouter panel 22′ and theinner panel 22″ are connected by screws 19 (FIG. 18 ) secured to bosses (not shown) on the inside of theouter panel 22′. Latch handles 23 (only one of which is shown inFIG. 1 ) at both sides of thefront door 22 are used to unlatch thefront door 22 from the remainder of thehousing 21. The upper portion of thehousing 21 haskeys 24 and adisplay 25. Thedoor 22 mounts a label roll holder mechanism generally indicated at 26 with opposed annular projections 27 (only one of which is shown inFIG. 2 ). Theannular projections 27 are received in the central opening of a label roll (not shown). Aplaten roll 28 mounted on acentral shaft 29 on which bearings are received. Agear 31 is secured to one end portion of theshaft 29. The latch handles 23 form part of a latch generally indicated at 32 which includeslatch hooks 33. Thedoor 22 is pivotally mounted to the rest of thehousing 21 by ahinge pin 34. Theprinter 20 is powered by arechargeable battery 35. - With reference to
FIG. 3 , theplaten roll 28 is driven by gearing 31′ (FIG. 4 ) which meshes with thegear 31. Thegearing 31′ and in turn thegear 31 are driven by anelectric motor 36. A print head 37 (FIG. 3 ) is mounted by aholder 38 pivotable about apin 39. Acompression spring 40 urges theholder 38 and theprint head 37 counterclockwise inFIG. 2 toward theplaten roll 28. A roll R of a composite web C is comprised of a carrier web W to which labels L are releasably adhered. In the strip mode shown inFIG. 3 , the composite web C is paid out of the roll R as the drivenplaten 28 rotates during label printing on the labels L. The carrier web W and the labels L pass over adelaminator 41. Thedelaminator 41 is shown to be a peel bar, but alternatively, thedelaminator 41 can comprise a peel roller (not shown). Thesprings 40 urge theprint head 37 against the composite web C which passes against theplaten roll 28. Thedelaminator 41 is disposed downstream of the place where theprint head 28 exerts pressure against the composite web C and theplaten roll 28. In the strip mode, thedelaminator 41 is ineffective to peel labels L from the web W. In the peel mode illustrated inFIG. 5 , the carrier web W passes from thedelaminator 41 to between apressure roll 42 and theplaten roll 28 and from there the web W exits theprinter 20. - With reference to
FIGS. 6 and 7 , and initially toFIG. 6 , thepressure roll 42 is shown to be mounted on a holder orcarrier 43. Theholder 43 hasarms 44 withsnap sockets 45. Thepressure roll 42 is of one-piece molded plastics construction and hasstub ends 46 received in thesnap sockets 45. Thepressure roll 42 is free to rotate in thesnap sockets 45. Thearms 43 also mount a tear bar 47 having a tear edge 48. Thearms 44 are joined to a transverse section ormember 49. Joined to thesection 49 are a pair ofarms 50 spaced apart more widely thanarms 44. Thearms 50 haveguides 51 which through-holes 52 (FIG. 7 ).Pins 53 have heads 54. Thepins 53 are slidably received in through-holes 52. Compression springs 55 received on thepins 53 bear againstheads 54 and againstshoulders 56 of theguides 51. Thepins 53 havegrooves 57 which receive E-rings 58. Thesprings 55 are preferably in slight compression when E-rings 58 abut shoulders 59. Thesection 49 hasposts 60 andannular projections 61 spaced outwardly of theposts 60. Compression springs 62 are received about theposts 60 within theannular projections 61 so that the springs are located with respect to theholder 43. Theholder 43 also has a pair of outwardly extending pivots orposts 63 snapped into sockets 64 (FIG. 4 ). It is noted that thepivots 63 are between thepressure roll 42 and the places where thesprings 62 bear against theholder 43. Thesprings 62 bear against the housing as shown inFIGS. 3 and 5 and are normally under compression as they urge theholder 42 counterclockwise to the position shown inFIG. 3 . It is noted that in this position, theheads 54 of thepins 53 are out of contact with positionable stops oractuators 64. InFIGS. 3 and 10 thestops 64 are in the ineffective positions out of contact withheads 54, and accordingly, thestops 64 have no affect on theholder 43. Thesprings 62, therefore, set or control the position of thepressure roll 42, namely, thepressure roll 42 is urged out of pressure contact with theplaten roll 28. In theFIG. 3 position, thepressure roll 43 is out of contact with theplaten roll 28. This reduces drag on themotor 36 in the strip mode depicted inFIG. 3 . -
FIG. 5 is likeFIG. 3 except that inFIG. 5 theholder 43, thepressure roll 42 and thestops 64 are in their peel mode positions. InFIG. 5 , thehead 54 is shown to abut thestop 64, and thespring 55 is more compressed than shown inFIG. 3 . The forces of thesprings 62 are overcome and thepressure roll 42 are shown in pressure cooperation with the carrier web W and theplaten roll 28. In particular, thepressure roll 42 is in pressure contact with the carrier web W and the carrier web W is in pressure contact with theplaten roll 28. Thus, the carrier web W is sandwiched between thepressure roll 42 and the drivenplaten roll 28 downstream of thedelaminator 41. Accordingly, rotation of theplaten roll 28 advances or moves the carrier web W so that the leading label L is peeled from the carrier web W at thedelaminator 41. The carrier web W exits the printer through thespace 77 between thetear bar 76 and thetransverse section 49 of theholder 43. By simply repositioning the stops from their ineffective positions (FIGS. 3 and 10 ) to their effective positions (FIGS. 5, 9 and 14) theprinter 20 can be changed from its strip mode to its peel mode, and vice versa. - The stops 46 are identical. Each
stop 46 is pivotally mounted on apin 90 for movement between the peel mode position shown inFIGS. 9, 14 and 16 and the strip mode position shown inFIGS. 10 and 15 . The housing has a pair ofprojections 91 that fit between pairs ofabutments stop 46 is in the peel mode position (FIG. 14 for example). Both sides of thestops 46 are the same although only one side is shown, each side having a pair ofabutments respective projection 91. In that thestops 46 and thehousing 22 in which thestops 46 are pivotal are constructed of plastics material, thestops 46 can be pivoted clockwise from theFIG. 14 position to theFIG. 15 position, and there is enough yield or give between theprojections 91 and theabutments 93 to enable such pivotal movement. The stops 15 can be returned from theFIG. 15 position to theFIG. 14 position by theabutments 93 and theprojections 91 yielding. Theprojections 91 and theabutments stops 46. - The
holder 43 and thepressure roll 42 are each of one-piece molded plastics construction. - With reference to
FIG. 8 , thelabel roll holder 26 includes a pair ofholder members 78 each having a straight gear orrack 79. A gear 80 rotatable on a stud secured to the housing is coupled to theracks 79.Screws 81 secured to thehousing 21 are connected to tension springs 82. The tension springs 82 are also connected to theholder members 78 as best shown inFIG. 8 . Theholder members 78 mount opposed identical, roll-engagingmembers 83 between which a label roll R is held. Themembers 83 are preferably rotatable onholder members 78 to minimize the drag on the motor as the label roll unwinds upon rotation of theplaten roll 28. Thesprings 82 pull on theholder members 78 andurge members 83 toward each other. The arrangement of thegear 89 andracks 79 causes theholder members 78 and themembers 83 to move relatively toward and away from each other when manual force is applied againstholder members 78 or themembers 83. - The
housing 21 has acompartment 95 for a radio (not shown) and acover 96 securable to thehousing 21 for closing off thecompartment 95. - The print head module M mounted in the
housing 21 includes themotor 36,print head 37,holder 38,pivot 39,spring 40 and gearing 31′ and is shown in assembled form inFIG. 13 . The module M is a subassembly which can comprise, for example, an LTP V Series thermal printer mechanism of Seiko Instruments, Inc. - Other embodiments and modifications of the invention will suggest themselves to those skilled in the art, and all such of these as come within the spirit of this invention are included within its scope as best defined by the appended claims.
